Helped me do the replacement, Thanks
mine is DHP454, so brushes for this one is same as BHP454?
This guy sounds like the "Engineering Explained" youtuber
The brush holders in mine are full of melted plastic
My brushes were practically glued on, it was not this easy to remove.
Yes same. How did you do it?
Struggling to remove the brushes as they are stuck in the holders. I’ve broken them and the wires ripped right off too. Any tips are appreciated
@@hamstersmailman5517did you figure out how to get bushings out? Same thing happened me
@@pafox3203 I’m afraid not, if you do lmk
I had this same problem and fixed it although my drill is still having issues so take this with a grain of salt.
I removed the plastic that the brushes are attached to from the armature (part the brushes make contact with) and seperated them from the drill body. That way I could push my worn brushes out the bottom of their housing (wire ripping off brush in this process but not needed anyway as new ones being installed). Through this process I noted inside the brushes housing particularly up the top closest to the armature side had some sort of plastic gunk or glue which I assume could be melted plastic due to the heat and friction. I grabbed a small phillips head screwdriver and pushed down upon the blocked gunk preventing the brush from going into the housing until it gave way and fell out of the housing. Now the brushes went into their housing and were able to be connected.
All this said, my drill started working although there were sparks coming from the brushes and motor and then the drill would stop working so I likely have another step or two ahead of me
Why in gods name is he using an impact driver for the brush cover screws?
Didn't have to listen to 2 or 3 minutes of annoying pseudo-music like most how to videos. NIce!
